Bernie Sanders is the most popular US senator in their home state in the country, according to a new survey of voters in individual states. Elizabeth Warren? The reaction is more mixed.

The latest Morning Consult survey of the approval rating of all 100 senators in their home states showed that residents of Vermont and Maine really like their senators, while those in other New England states, including Massachusetts, give their senators a less enthusiastic approval.

Meanwhile, Kentucky’s Mitch McConnell, the Senate Republican leader, is the least popular among voters in his home state.

Other senators in the top 10, approval-wise, include Vermont’s second senator, Patrick Lahey and both Maine senators, Susan Collins and Angus King. While Sanders can use his 75 percent approval rating at home to look towards another potential presidential campaign, Collins’s high approval rating might matter more at the moment, given her swing-vote role in the Senate’s health-care debate.

The rankings were compiled from nearly 175,000 interviews with registered voters across the country from April through June 2017. The survey asked if they approved or disapproved of their senators’ job performance.

Massachusetts residents gave the state’s other senator, Ed Markey, a 55 percent approval rating, with 22 percent disapproving. Nearly 1 in 4 of Markey’s constituents said they didn’t know how they felt about him.

In New Hampshire, residents gave nearly identical approval ratings to senators Jeanne Shaheen (54 percent) and Maggie Hassan (52 percent). In Rhode Island, both senators were around the critical 50-percent mark in approval ratings. Jack Reed had a slightly higher rating with 51 percent; fellow Democrat Sheldon Whitehouse was at 46 percent.
